The Forerunner 910XT is the perfect training partner & is the only all-in-one, GPS-enabled device that provides detailed swim metrics & tracks distance, pace, elevation & heart rate&185; for running & cycling. It sports a sleek profile, comfy wristband & an easy-to-read display. The 910XT Tri Bundle is compatible with ANT+™ sensors, including the speed/cadence sensor (for cycling), & the premium heart rate monitor (both included). You can pair the 910XT with an existing ANT+ heart rate monitor or purchase as an accessory. Whether you’re training or racing, every second counts, so the 910XT makes it easy & seamless to transition between sports. The auto multisport feature lets you switch sport modes with just 1 button press, so you don’t lose precious seconds in transition. The quick release mount (supplied) means that you can move the 910XT easily from wrist to bike. Designed for open water & pool swimming, Forerunner 910XT is water resistant to 50m (164ft). It’s Garmins first multisport watch to offer extensive swim metrics, including swim distance, stroke identification, stroke count & pool lengths. It also computes your swolf score to help you gauge your swimming efficiency. (Swolf is a combination of the words ‘swim’ & ‘golf’ & it is a way of calculating a swimmer’s efficiency. To find your Swolf score your lap time is added to the number of strokes you have taken. Eg. if it takes you 20 seconds to swim a lap & you took 15 strokes your score would be 35.) The 910XT’s robust design & easy operation make it suited for other water sports, including paddle boarding. Because it’s GPS-enabled, Forerunner 910XT even captures the path you travelled so you can view it later on a map in our free online community, Garmin Connect™. This feature can help you analyse your open water swimming & adjust your technique as needed.
